Cannot buy land or money from the system

I have a diva-r24886 (0.8) running on WAMP (windows 7 64bit):

Apache 2.4.9
PHP 5.5.12 (Curl and XML-RPC enabled and working)
MySQL 5.6.17
Static IP URI: 50.247.123.201:8002

I've downloaded and installed the money server successfully. Balances update correctly, i can pay and be paid, group creation is correctly charged, and i am apparently able to setup land sales.

For some odd reason, the helper scripts won't work when it comes to buying money from the system (i have setup a banker avatar) or buying land.

When attempting to buy a parcel for sale, or buy money from the viewer, nothing comes up in either the OpenSim console or the MoneyServer console.

A comment about the helpers script on the download page says they don't work in PHP 5.3. Does that mean every newer version of PHP cannot be used to successfully setup helper scripts? What about PHP 5.6 and up?

Thanks in advance
